This topic is a nice recap from my book "Escape from Paradise" from the chapter entitled "Death may be the easiest way."
Page 208 says "...many hundreds of thousands, perhaps millions, do leave the Watch Tower organization... However, there are only four ways to leave the Jehovah's Witness faith once you ave been baptized into it, and none of them are pretty. These are: disfellowshipping, disassociation, fading, and death."
The entire chapter is dedicated to explaining all the variations of each of these ways and how they affect those who have to go through whichever way their situation takes them.
This chapter was written primarily for those who are not associated with the JWs so they can understand what we ex-JWs had to go through, as well as to memorialize those among our families and friends who decided that death was the easiest way out.
